My mom has a mixed breed dog that goes after mostly everyone. I have been telling her for years she needs to do something. Training itself was to big of an expense. I seen the Pet Resolve Dog Training Color and thought of her.
She has been using it to train her dog from all the barking. She is a big dog and the collar fits perfect. It took a while to learn but well worth it. I helped her at first learn how it works. It has a remote which is very helpful. She is actually barking much less now and learning. In time she will teach her to be more nice to people that come to the house. If you have a problem dog I recommend this. I have 2 small dogs but it is much to large to try on them. I received this product complimentary in exchange for my unbiased review. All words and opinions are my own.
